The story takes place in the mortal world on the border of the mirror universe. The protagonist Yu Zhuoyue was originally the kitchen god of heaven. Because he questioned the rule of heaven that "incense determines destiny", he was deprived of his godhood and demoted to a 53-year-old mortal woodcutter. He started from the bottom and resumed his spiritual practice as a middle-aged man. He unexpectedly discovered that he had the "Gluttonous Devouring Heaven Bloodline" that could swallow the law. In the process of practicing "Great Sun Burning Celestial Body" and "Holy Dao Zhaoming Lu", he met Su Wanqing, a strange woman who intended to revolutionize the world of cultivation but was caught by the miasma of the Ziwei Emperor Star, and his old friend "Fate Guardian" Xuan Jing who believed in fate and guarded the established trajectory. Yu Zhuozhou is involved in the conflict between the conservatives, the reformists and the forces of destiny. His existence itself is the biggest challenge to the "established destiny". He needs to find his true heart in the Six Rhythms of the Sword Sound, transcend his bloodline in genetic purgatory, and use the clues of the Chaos Sky-Opening Ax to split the fog of destiny shrouding the world. In the end, he did not choose to return to the throne of God, but found the destination of "the fire of the heart is the divine fire, and the original heart is the avenue" in the origin of the mirror image. As a mortal, he opened up a new path that does not rely on incense and only asks about the original heart. ",
